This four-part article series provides an in-depth discussion on what the “All-on-4” technique is, how it works and its benefits over other traditional tooth replacement technologies.
Welcome back to our four-part article series on “All-on-4” dental implants and how this breakthrough technique enables patients to get a full set of new teeth in as little as a single day. In our previous article post, the first installment of the series, we provided a brief introduction by looking at tooth loss statistics in the United States. We saw that a staggering number of people – 33 million to be precise – are currently living without a single original adult tooth left in their mouths and that a further 100 million people have lost between 11 and 15 of their teeth. We then introduced Dr. Paulo Malo – the European implantologist who innovated a far more sophisticated solution to rampant tooth loss and edentulism (the state of being toothless)… “All-on-4” implants.
In this article, Part 2, we shall examine exactly how the “All-on-4” protocol works and the procedure required to place it.
What is the “All-on-4”?
The “All-on-4” is a technique for the replacement of entire arches of missing teeth using dental implants. Take a look at the picture below…
This picture explains the concept behind the “All-on-4” and how the technique works. During a single surgery, an implant dentist inserts four dental implants in the mouth: two near the front of the mouth and two near the back, in the region of the third molars. These implants are then used to support a dental prosthesis, which is customized to fit the patient’s mouth snugly and comfortably. The prosthesis is also expertly fabricated to precisely resemble a complete set of natural teeth and because it is anchored to dental implants, it is fixed, non-removable and cannot slip around or fall out!
Bone Loss and Over-Coming the Need for Bone Grafting
The placement of the four implants is carefully and precisely planned beforehand with the use of sophisticated 3D Cone Beam CT and imaging software. This planning ensures that the dentist can reap maximum support from what remaining bone volume a patient has, while avoiding damage to vital structures, arteries and nerves in the patient’s mouth.
What causes bone loss in the jaw?
Being toothless and wearing dentures has several consequences for a patient’s health and comfort. One of these consequences is the loss of bone volume in the jaw. Without the tooth roots to keep the jawbone stimulated and alive, this hard tissue atrophies and wastes away from disuse. This remodeling process is what necessitates the refitting of dentures every few years or so and it’s also what causes a patient’s face to look increasingly sunken, aged and collapsed around the mouth.
In most cases, when patients do finally come to the implant dentist to have “All-on-4” dental implants placed, they’ve spent several years being toothless and have, as a result, lost supporting bone volume. Through the careful orientation and angulation of “All-on-4” dental implants, dentists can provide enough support for a new set of teeth, typically without having to perform bone grafting surgery beforehand. This saves tens of thousands of dollars on the cost of such a procedure and the many, many months that patients would otherwise have to spend in recovery.
Avoiding the need for bone grafting in most cases is what makes it possible for “All-on-4” dental implants to give patients new teeth in a day.
